We are looking as Sellacious as a solution for our online marketing needs.

I need to know if our ordering structure will be possible with Sellacious.

1. Our customer will be selecting a product type, size, and quantity. From there they will need to add their digital artwork to the item. I need to be able to show that art as the items image in their cart. (Something like this -- https://www.stickeryeti.com/)
2. Can you add options to the product that effect the price. (eg. If you were selling shoes but wanted extra laces. Could you add a custom amount of laces for a set cost?)
2. Also, will they be able to have an account that they would be able to re-order past orders?
3. When we ship an item will we be able to add a tracking number to the order so that our customer could log in and see it.
4. Would we be able to adjust a price (Refund / Charge More) for an order after the order has been placed?
5. Once a job is complete, would we be able to move the job backwards in production if we had to redo a job, OR duplicate the job as a reproduction?
6. Is there a way to generate an order and put it in particular customers profile. (eg. Create a reproduction of their passed order but not charge them)
7. How much control will I have over the appearance of the site. Am I restricted to the predefined templates or do I have control over the CSS/HTML of the pages?
8. If using the Stripe plugin, would refunds be controlled from our admin end of our site or would we have to do that manually through Stripe?
